Scientific Name | Erica orthiocola E.G.H.Oliv. |
Higher Classification | Dicotyledons |
Family | ERICACEAE |
National Status |
Status and Criteria | Endangered D |
Assessment Date | 2007/02/09 |
Assessor(s) | E.G.H. Oliver & R.C. Turner |
Justification | An extremely localized (EOO 2.75 km²), high altitude habitat specialist. Only one small subpopulation of fewer than 200 plants is known. Potentially threatened by alien Pinus invasion and too frequent fire. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Endemic to Pilaarkop, Riviersonderend Mountains. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | South Sonderend Sandstone Fynbos |
Description | Fynbos, on damp, south-facing rock ledges. |
Threats |
| The southern slopes of the Riviersonderend Mountains is severely infested with alien invasive pines, posing a threat to many localized endemics. Invasive pines are already present on the lower and middle slopes of Pilaarkop and is likely to cause a decline in the population of this species if allowed to spread to the summit. |
